Fastening/Assembly Technology

Sheetmetal-Clinching Products Unveiled at EuroBlech 2008

Tox Pressotechnik GmbH & Co. (with U.S. headquarters in Warrenville, IL) introduced two new fastening systems at EuroBlech. Its new Tox-Micropoint sheetmetal-joining technology allows fabricators to join small sheetmetal parts such as contact elements, springs and similar components (Fig. 1) made of steel, copper or aluminum with single sheet thicknesses from 0.1 mm to a total sheet thickness of 1.2 mm. Electric conductivity is retained in the joint, making the technique suitable for electric and electronic assemblies such as contact tabs, switch contacts and rockers.

Tox also introduced to the EuroBlech crowd its new Twinpoint dual-punch joining system (Fig. 2-3) for small parts where optimum retaining forces are required. Twinpoint joins thin (0.2 mm) steel sheets, aluminum, copper and specialty-steel sheets to a total thickness of 11 mm.
